Review: Talk about Customer Service these guys went above and beyond what most companies do these days. Asked him about shipping and the model. He got back to me under 5 minute. Had it shipped out the SAME DAY EVEN !!! I received the Wideband a day earlier than expected. AEM makes great products. I custom make Gauge clusters for cars. This is for my personal car. So STOKED To get it installed.
Review: Works great, no issues after a year. would recommend buying the AEM stainless bung with it. Its worth the extra money
